Post has long extra html

I sent an email from Gmail to an Yandex account. The email had two lines of text with a couple of words in bold (to force html formatting).

Postied created post in wordpress using the imap fetch. however, it included a very long HTML with inline CSS.
Appreciate any assistance.
